In this fifth installment of our series on conversational usability, our focus shifts to conversational usability and the process of evaluating and improving conversational interfaces that often differ significantly from the visual and physical interfaces we normally use to test with end users.

In this fourth installment of our series on conversational usability, we're turning our attention to conversational content strategy, an underserved area of conversational interface design that is rapidly growing due to the number of enterprises eager to convert the text trapped in their websites into content that can be consumed through voice assistants and chatbots.

Although JSON Web Tokens (JWT) is a younger specification than its more well-established cousin, OAuth 2.0 Bearer Token authentication, JWT has been adopted by quite a few in the Drupal community due to its relative simplicity. In this installment, we explore JSON Web Tokens and how this authentication mechanism can benefit your decoupled Drupal architecture.

Over the last few years, I have had the privilege of sharing insights and tutorials on decoupled Drupal, which was originally unknown territory with shifting sands but today is a widely adopted approach, including by some of Acquia's most influential customers. Nonetheless, the relative unavailability of developer-focused resources that are both authoritative and current has hindered architects' and developers' ability to evaluate and explore decoupled Drupal for themselves.

Though there was no DrupalCon Europe this year, the European Drupal community stepped up and organized their own conference, Drupal Europe, in Darmstadt, Germany last month. An incredibly successful gathering held in the Darmstadtium venue, a beautiful convention center in the center of this college town, Drupal Europe demonstrated the unique power that grassroots initiatives can have in our open-source community.

“Digital Experiences” are the next big thing someone at your company is almost certainly talking about. These include visionary technology that operates based on rich data that is timely and location-based, interactions between other services and products, and perhaps most importantly: content that is not reliant on a user manually driving the experience (as they usually might on a website or mobile application). This article discusses a unique digital experience, thousands of countdown clocks, developed in Drupal 8 by Acquia for New York's Metropolitan Transportation Authority (MTA).

When Drupal 8.0 was released two and a half years ago, with a built-in REST API, it signaled the start of Drupal's evolution to an API-first platform. Since then, each of the five new releases of Drupal 8 introduced significant web service API improvements. Drupal 8.6, shipping in September, will also have a new bunch of API improvements.

In Lisbon, steep slopes and sweeping vistas towering over placid waters and crowded ports characterize the topography of one of the most beautiful cities in Europe.

This year, the Portuguese capital played host to Drupal Developer Days, possibly the most important event for developers specializing in Drupal. Held at the University Institute of Lisbon, it was a conference not to be missed, with innumerable insights from Drupal core contributors and maintainers.
